NASHVILLE, TN (AP) - Three Republican longshots challenging President Donald Trump in 2020 made a roadshow stop in the liberal-leaning capital of pro-Trump Tennessee.

Former Massachusetts Gov. Bill Weld, former South Carolina Gov. Mark Sanford and former Rep. Joe Walsh of Illinois drew a sparse crowd Saturday at the Politicon conference in Nashville. The event attracted several hundred people in a room with more than 2,000 seats.

The three disagreed on the impeachment inquiry. Weld and Walsh expressed support for impeachment. Sanford said a censure could be a better option, contending that a likely acquittal in the GOP-led Senate could benefit Trump politically.

All three oppose decisions by several states to cancel the 2020 GOP presidential primaries.
