no, radical policies wont drive election winning turnout
“an analysis using data from the States of Change project, sponsored by, among others, the Brookings Institution and the Center for American Progress, indicates that, even if black turnout in the 2016 election had matched that of 2012 (it dropped from 62 to 57 percent), Clinton would have still lost. On the other hand, if she had managed to reduce her losses among white noncollege voters by a mere one-quarter, she’d be president today. That’s an issue of persuasion, not turnout.”

“In 2016, the age cohort that really killed Democrats was voters ages 45 to 64, who had split evenly in 2012 but leaned Republican by six percentage points four years later.”

“it’s a mistake to assume that Democrats would benefit disproportionately from high turnout. Trump is particularly strong among white noncollege voters, who dominate the pool of nonvoters in many areas of the country, including in key Rust Belt states. If the 2020 election indeed has historically high turnout, as many analysts expect, that spike could include many of these white noncollege voters in addition to Democratic-leaning constituencies such as nonwhites and young voters. The result could be an increase in Democrats’ popular-vote total — and another loss in the electoral college.”

“Stanford political scientists Andrew Hall and Daniel Thompson, for example, studied House races between 2006 and 2014 and found that highly ideological candidates who beat moderates for a party nomination indeed increased turnout in their own party in the general election — but they increased the opposition turnout even more. (The difference was between three and eight percentage points.) Apparently, their extreme political stances did more to turn out the other side to vote against them than to turn out their own side to vote for them.”
