Trump didn't need to convince one Hillary voter to come over to his side.
Trump canít afford to lose even 3 percent or 4 percent of the Republican base or heíll go down this fall - but Trump already has.
Trump is getting the same percentage of Republican voters as he received back in 2016. 88% according to the polls with the trial heats between Biden and Trump. Hillary received 8% of the Republican vote in 2016, Biden is averaging 6% so far. So it's not Republicans that are or have deserted him. 90% is the historical average for a presidential candidate percentage of his party's votes in any one election.
Trump's loss so far is among independents, in 2016 Trump received 46% of their vote vs. 42% for Hillary. 12% voted against both major party candidates. Trump is averaging 40% as of today among independents. To round this out, Trump received 8% of the Democratic vote in 2016, he's getting 4% today.
This explains where thing stands today, but where they stand in November, who knows?
It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
