WASHINGTON -- Tuesday's primaries sent one message loud and clear: Democrats are in deep trouble, and Republicans are headed for substantial gains in the midterm elections.

The ideological battle lines that emerged in the three major party Senate primaries in Pennsylvania, Arkansas and Kentucky could not be more favorable for the GOP's anti-incumbent, tea party-driven, "take-back-our-country" campaign offensive.

Candidates on the Democrat side were dyed-in-the-wool leftists who were in lockstep with Barack Obama's expand-the-government health care plan and other budget-busting bills, no matter how deeply they will plunge our country into further debt and insolvency.

The Republicans who won their primaries are budget-cutting, tax-reducing, anti-Obamacare conservatives who embraced the anti-Washington mood of the country and intend to push Congress in a sharply new direction.

With little more than four months to go before the Nov. 2 elections, here's what these contests tell us about the shape of the political landscape:

PENNSYLVANIA: Let's start with the game-changing prospect of a conservative Republican winning in a major Democratic state in the heart of the Northeast.

Former Congressman Pat Toomey, a conservative Republican who narrowly lost an earlier bid for the Senate, will be facing Rep. Joe Sestak, an ultra-liberal who voted with Nancy Pelosi and her left-wing gang 98 percent of the time (including Obamacare) and never met a big-spending bill he didn't like.

The big issues in this race will be Sestak's reckless voting record of higher taxes and massive debt and his cozy alliance with far-left groups like, who support his campaign.

Toomey has led Sestak in all the polls for the past year, but the race is expected to tighten up and is rated a tossup by most election analysts. But independents have fled the Democrats in droves in the state, as have seniors angered by Obamacare carving $500 billion out of Medicare benefits.

KENTUCKY: Tea party conservative hero Rand Paul perfectly fits the political profile of this state in the age of Obama. He trounced the party's establishment choice, Secretary of State Trey Grayson, by 23.4 percent and is well-positioned to keep the state's seat in GOP hands.
