AUSTIN, Texas — Establishment Republicans fell to tea party insurgents in Indiana and Nebraska. Could the same happen in Texas?
Political insiders nationwide will be watching Tuesday when long-serving Lt. Gov. David Dewhurst squares off with tea party favorite Ted Cruz.
Both are seeking the Republican nomination to replace retiring U.S. Sen. Kay Bailey Hutchison.
It could be another incarnation of Indiana voters rejecting Senate veteran Richard Lugar, and Nebraska state Sen. Deb Fischer upsetting two better-known U.S. Senate candidates.
Cruz says he's more conservative then Dewhurst. Dewhurst counters that national tea party groups are meddling in Texas politics.
The contest headlines 170 major competitive races statewide.
