U.S. Senator Mitch McConnell is shrugging off suggestions that the Republican Party lacks unity after former GOP presidential candidate Ron Paul declined to endose Mitt Romney and left the party's Tampa convention.The Kentucky Republican was asked about it during Politico's Playbook Breakfast. The interview was broadcast on C-SPAN.McConnell says what matters is that his Senate colleague, Rand Paul, the son of the Texas congressman, has endorsed the Republican presidential nominee."In our state, not surprisingly, he is very well known and has been successful and is the next generation of the Paul family. So we’re pleased and proud to have his support and I think it makes a big difference, and I think we’ll get the vast majority of those who were enthusiastic about Congressman Ron Paul. After all, they don’t want to elect Barack Obama," he said.McConnell added that if he becomes majority leader of the Senate next year, the repeal of the national health care law will be among his top priorities.
