Lessons to be learned from the primary elections...

Here are some lessons hopefully learned from the primary elections on Tuesday for all of those whose influence was rejected.

• In Pennsylvania, progressive Democrat Joe Sestak defeated former Republican and new centrist Democrat Arlen Specter. The lesson is for President Obama and his awful centrist advisers and for Democratic Pa. Gov. Ed Rendell and fellow party bosses everywhere (and throw in the national TV media too): The Democratic voters don't need a political movement, like the Tea Party, to know how to reject the do-nothing lackies and incumbents in the center. They know why they want to vote for progressives on the left, like Sestak, who have ideas and want change like the voters want. Obama was one of those progressive candidates at one time, but he's sat around in the Oval Office listening to the crap of Clinton advisers too long. It has stunted his growth. Recommendation for Obama: The title of the Beatles song: "Get Back." And dump some advisers. Recommendation for Rendell: Retire, like Specter.
• In Arkansas, Democratic centrist Blanche Lincoln got the most votes but not enough vote to keep her from a run-off election with progressive candidate Bill Halter. In that way, Halter won, and will probably win the run-off election. The lesson is for the Clintons and the political establishment everywhere: Progressives generate energy among voters. Centrists are rejected.
• In Kentucky, the Democratic candidate Jack Conway won on the Democratic primary side with many more votes than Rand Paul, the winner on the Republican primary side. But the Paul vote should provide for some lessons, as the Republican establishment candidate who lost to Paul was the candidate supported by Senate Republican leader Mitch McConnell. The lesson is for Republican leader Mitch McConnell, who is under the false notion that voters want Republicans to replace Democrats. No, it looks like voters want people of change to replace people of the establishment or incumbents who are stuck in the middle-nothing, dilution-pollution land of politics. Rand represented the libertarian vote, and was a so-called Tea Party candidate. But many of his foreign affairs views from the Libertarian perspective are rather progressive, such as wanting an end to the two wars and drug decriminalization. Paul will lose, though, because his domestic ideas are way too conservative. The Democratic candidate will win and let's hope he knows better than treading down the center when it comes to issues. Recommendation for McConnell: Retire. And the faster, the better.
