JEFFERSON CITY — In what could be one of their final votes of the 2019 legislative session, it appears increasingly likely state lawmakers will call for a do-over when it comes to changing the way Missouri draws its political maps.

In a hearing Tuesday, the two top leaders in the Republican-controlled Senate heartily endorsed a ballot initiative seeking to overrule Missouri’s new voter-approved redistricting process and return to a system containing many of the state’s old methods.

At issue is fallout from the approval of the “Clean Missouri” referendum in November, which, along with tightening state ethics rules, imposed a new redistricting process that would be run by an individual state demographer.

The aim of the changes were to stop gerrymandering, in which state House and Senate districts are drawn to favor a party or particular candidate for office.

But Republicans view it as a way for Democrats to win more seats in the Legislature.
