This is the difference between the right and the left. The country has in the last forty years or so become increasingly conservative and both political parties have moved to the right.
		
		
	 
What have you been smoking? Democrats have been moving to the left pretty hard. Sanctuary cities? Decriminalize illegal border crossings? Medicare for all? Increase minimum wage to $15/h nationwide? Pay reparations to blacks? All of those are left wing policies. 
Then come things like Hillary inviting mothers of young black men who have been shot by police to the DNC convention; never mind that most of these shootings were justified.
Bill Clinton sounded almost like Trump on the matter of illegals and Obama is being attacked for deporting illegals.  
And while Clinton rightly condemned Sista Souljah's racism, I have a feeling that most of this crop of 2020 hopefuls would applaud her and accuse why whites who dare disagree 
	
	
		
		
			This means that the Republican party has become more extreme and the Democratic party has become more moderate. Anyone supporting the Republicans or calling themselves conservatives today can't escape the simple truth that they are aligning themselves with extremists.
		
		
	 
There is extremism on both sides. The El Paso shooting is an inappropriate reaction to what's been going on at the border, with ~100,000 mass migrants coming each month and demanding to be let in, and the Democrats who would let them all in.
		
 
		
	 
Has the Democratic Party swung violently to the left or is that the way that you view it from where you are sitting on the extreme right? I think that it is the latter. 
Most of the examples that you gave of the Democrats moving to the left are talking points straight out of whichever right-wing disinformation site you prefer currently. 
The Democrats don't support open borders or even want to encourage illegals because illegals are willing to work for lower wages which lower the overall wages for US workers. If you want to see who encourages illegals, pay attention to this simple rule - follow the money, who profits from the illegal immigrant workforce? 
The number of illegals working in the US started to jump after the Reagan amnesty bill of 1986. Do you know why? Was it because so many illegals wanted to be in on the next amnesty bill? Or was it because the Republicans wrote a huge loophole into the 1986 bill making it much easier for companies to hire illegals without any fear of being prosecuted for it? 
Medicare for all is being proposed to lower the costs and to expand the people who have access to health care. The private for-profit health insurance companies are extremely inefficient delivering health care to our people. Since we turned health care over to the for-profit companies starting in the 1980s health care costs have soared encouraged in no small part by the health insurance companies because it is the one sure way to increase their profits. Once again, follow the money, who profits from for-profit companies taking over the health care industry? 
Sanctuary cities exist because it is a very bad idea to use the local police to enforce immigration misdemeanor laws because the local police need the cooperation of all of its citizens to solve serious local crimes, even the illegals. If the local police help ICE and the border police any chance of this cooperation will evaporate. The border police are now the largest police force in the US. It is hard to see why they have to have the local police to help them with their job. 
The Democrats have always opposed illegal immigration as you admit with the two examples of Clinton and Obama. Just like traditional liberals before the Democratic Party moved so far to the right opposed the free trade treaties so beloved by the Republican Party that you are defending. The treaties that were meant once again to put downward pressure on the wages in the US. Clinton and Obama also supported those treaties, unfortunately. But these are the signs that the Democratic Party has moved to the right, not to the left as your disinformation has convinced you. 
Other signs that the Democratic Party has become more conservative over the last forty years or so include Clinton embracing welfare reform, Obama willing to trade cuts to Social Security and Medicare for raising the debt limit, neither something that the Democrats of forty years ago would have ever considered. 
Why? Because the Democratic Party was much further to the left then and dependent on the support of the labor unions then, the labor unions that the Republicans all but wiped out in private industry. And why did the Republicans wipe out the labor unions in private industry? Answer it yourself, remember, follow the money. 
Do you detect a pattern here? These all are easily proven facts that are only countered by the lies that you have repeated here. 
The 15 dollars an hour minimum wage is also reasonable. It is about what the minimum wage would have been if the minimum wage had been indexed to inflation. 
Yes, Hillary was grandstanding by inviting people whose relatives had been shot by the police. I don't know if you have noticed but the Republican Party has elected a president whose only thing is grandstanding, he has nothing else.
