Donald Trump's President Campaign and his unwillingness to truly condemn David Duke and other neo-Nazis is what led to David Duke entering the Louisiana Senate Race. It reinforces my plan to write-in Ted Cruz for President in November, instead of voting for Trump. Duke's candidacy is exhibit A of the danger of Trump at the top of the Republican ticket.
As for Duke, he could easily win the Louisiana Senate Race. Duke has more name recognition than any of the other candidates. The other Republican candidates probably will divide the vote amongst themselves, which could open a path for Duke to be the Republican Candidate for Senate in a state that usually goes red in Presidential elections.
