Kevin McCarthy, Mitch McConnell and all of the wealthy establishment donors are openly lobbying Trump to place their golden girl on the ticket.
Lara Trump said in an interview when asked about Nikki Haley on the Trump ticket: "Never say never".
Trump himself has said that he gets along well with Nikki and that she did a good job as UN ambassador
This would be a nation ending mistake if Trump wins the general election against Biden and then the elites do a redux of JFK and then Nikki Haley automatically becomes President.
You are underestimating the importance of that. But even I agree I might not vote for Trump if Nikki is the VP. Sanders I don't have any opinion of - but the media hasn't been pushing her either so I don't know what most women voters would think.
