Radical plan urges Democrats to abandon their party to stop Trump

An action group is lobbying Democrats to drop their party allegiance and register as Republicans so they can vote in their state primaries to stop Donald Trump, The Sacramento Bee reported.

The plan, hatched by the non-profit group PrimaryPivot, doesn't have much of chance of success, according to political strategists. But it is gaining traction after being mentioned in more than one news report.

It does have some major pitfalls though, according to The Bee's Stephanie Finucane.

"For one, party switchers — or crossvoters, as they’re sometimes called — would need to agree on an alternate candidate, since splitting the vote among the remaining GOP hopefuls could still leave Trump on top," Finucane writes.

If voters were to go through with the plan, the best choice, according to Finucane, would be Nikki Haley — but if she were to defeat Trump in the primary, she could perhaps then go on to defeat Biden.

"All this is extremely hypothetical, because so far Democrats do not seem super inclined to change their political allegiance," Finucane writes.
