Really you don’t need to read more than one chart:
If you vote for anyone other than Harris, you’re voting for Trump:
Spoiler implies we would vote for a Democrat if there were no 3rd party options. We would not. There’s a larger chance you would vote for a republican than us voting Democrat
For you, personally, that may be true. Statistically speaking, in general, it’s very much the opposite:
https://www.thirdway.org/memo/the-data-how-third-parties-could-be-spoilers-that-elect-trump
“Similarly, Third Way’s polling has found that Biden’s voters are 13 percentage points more likely to consider voting for a third party than Trump’s voters. While Biden has a higher ceiling, with his possible vote totals well north of 50%, Trump has a stronger floor: his voters are more loyal, so third parties are less likely to draw them away.”
If you lean left, and you fail to vote for the Democratic candidate, you only help the Republican candidate.
There’s the confusion, we dont lean left, we are left. Democrat voters lean left then vote for non left leaning candidates. In rhetoric the DNC may sound like they lean left but in action they do not.
Compared to Trump, Nixon is to the left.
By Obama’s own admission, Nixon was to the left of Obama.
