As far as the Republican primary elections last Tuesday, it was a great night for establishment Republicans in Congress. With none of them losing with Representative Jim Lankford winning his primary overwhelmingly. But the biggest victory would have to be for Senator Tad Cochran who has been in Congress since 1973 when he was first elected to the House. In a really bad year for Congressional incumbents with Senator Cochran being one of the biggest porkers in Congress and perhaps the biggest porker in the Senate. Winning his primary against a Tea Party favorite because African-Americans voted for a Mississippi Republican.
As far as Speaker John Boehner's suit against President Obama. This reminds me of when the Speaker back in 2011 decided to take up the defense of the Defense of Marriage Act that the Obama Administration decided not to defend. Then the Speaker appointed some Republican representatives to defend the law in court. With a lot of people in both parties pretty much deciding that DOMA was dead because of the makeup of the Supreme Court when it came to homosexuality and privacy. And with recent Federal curt decisions going against DOMA. The Speaker's suit is just as dead because it will probably never even be heard in court at least not while Barack Obama is still President.
As far as the missing IRS emails. The IRS already has a great person running the IRS who has a lot of respect from both political parties. (Perhaps Tea Party not included) They already have multiple investigations into this issue and the Justice Department is looking at it as well. So another House investigation into it looks like more wasted taxpayer money on the behalf of House Republicans. A skill they mastered during the Bush Administration wasting taxpayer money.
