Texas Republicans have a door-knocking campaign going on this weekend, encouraging their grass-roots folks to get out and gather names of people who might vote with the GOP in November.

Their pitch to volunteers is that Democrats are jazzed up this year and the Republicans need to catch up. They've got various officials — U.S. Sen. John Cornyn, Railroad Commissioner Michael Williams — promising to give $250 rewards to people who win drawings after turning in 60 new names.

• U.S. Sen. John Cornyn's campaign doesn't trust polls that show Democrat Rick Noriega only four points behind the incumbent. But they're using the scare to try to raise money. Their latest pitch: " The facts are clear, the extreme left is energized and unscrupulous, and our opponent is shamelessly aligned with them and will say and do anything it takes to gain much needed relevance and resources." Two separate polls had Noriega just behind Cornyn; and both, like others we've seen, had Cornyn holding less than 50 percent support.

• Midland Democrat Bill Dingus filed a friendly lawsuit against the Texas Democratic Party in an attempt to clear up his spot on the ballot. He was on the Midland City Council when he filed to run against House Speaker Tom Craddick. He's asking the state court to declare him an eligible candidate. No court date's been set.

• Texas Agriculture Commission Todd Staples is going to Cuba on a trade mission. He says he's the first statewide elected official from here to do that in 45 years. He'll take a couple of dozen people with him; they're trying to expand trade between Texas and the island.

• Pat Dixon, the state chairman of the Libertarian Party, is now an elected official after winning a spot on the Lago Vista City Council. He was on the council before, lost the seat in 2007 and will go back on.

• One of the best campaign finance websites — OpenSecrets.org — has been redesigned. It's faster, searches are better, and one of the truly great resources on the Internet is now even better. In about two seconds, we had our mitts on this: Texas ranks third among the states in total contributions to federal candidates in this election cycle, fourth in money given to Democrats, second in money given to Republicans, and first in soft-money contributions. Texans have contributed $90.6 million to federal candidates so far, with about three-fifths to Republicans and two-fifths to Democrats.
