Congressman Luke Messer emerged the victor Saturday of a straw poll of Republican U.S. Senate candidates.

The Republican race to decide the challenger to Democratic Sen. Joe Donnelly will be Indiana's top primary race.

Among Indiana's House delegation, the vote split evenly along part lines: the two Democrats voted no while all seven Republicans voted in favor.

Messer hit on several traditional conservative themes in his speech - fewer regulations, support for the Second Amendment, and an anti-abortion platform.

The tone of the race to challenge incumbent U.S. Sen. Joe Donnelly has been marked by vitriol between U.S. Rep. Luke Messer and U.S. Rep. Todd Rokita.

Rep. Todd Rokita (R-Brownsburg) formally joined the Senate race, becoming the sixth GOP candidate trying to unseat incumbent U.S. Sen. Joe Donnelly (D-Ind.).

The Indiana Democratic Party says a Congressional vote to repeal and replace Obamacare takes health care away from millions just to fulfill a political promise.

Lt. Gov. Eric Holcomb, U.S. Representatives Susan Brooks and Todd Rokita, and State Sen. Jim Tomes are all seeking the nomination.

Republican Sen. Jim Tomes sent an email to members of the Indiana GOP's state committee, announcing his intention to seek the Republican nomination for governor.

The Indiana Republican Party will choose its replacement for Mike Pence on the gubernatorial ticket in a little more than a week.
