Kentucky Secretary of State Alison Lundergan Grimes (D) told WHAS-TV that she might take Sen. Rand Paul (R) to court to block him from running both for president and reelection to the U.S. Senate in 2016.

Said Grimes: “The law is clear. You can’t be on the ballot twice for two offices.”

She added: “We’ll look to the court for any guidance that is needed. And at the end of the day, we’re not going to be bullied.”

Sen. Rand Paul’s (R-KY) “brain trust has spent months developing an exhaustive political and legal battle plan to ensure he can run for both Senate reelection and the White House in 2016—despite a Kentucky law that suggests otherwise,” National Journal reports.

“They have developed backup plans for their backup plans in an all-out effort to safeguard Paul’s Senate seat should he falter in the presidential sweepstakes. The contingencies range from changing Kentucky into a presidential caucus state to filing a lawsuit challenging the law, from daring Kentucky Secretary of State Alison Lundergan Grimes to keep him off the ballot to taking her out next November if she does.”

Paul told the Lexington Herald-Leader that while he was still “four to six months” away from making a decision about a White House run, “the one thing we’ve decided is that I’m definitely running for re-election.”
