Even if we throw aside the ample evidence from other states, we ask, what problem is Mr. Hogan trying to solve? Governors drive the gerrymandering bus in Maryland, and they would only do so more effectively under legislative term limits (unless a miracle occurs and the General Assembly adopts Mr. Hogan’s redistricting reform proposal). We may this year be dealing with a corruption case involving a long-term legislator, Sen. Nathaniel Oaks, but last year, authorities leveled corruption charges against one man who served less than a year in the House of Delegates and campaign finance charges against another before he was even sworn into the House. The current presiding officers of the House and Senate may have record-long tenures, but 40 percent of the House was new in 2015, along with 25 percent of the Senate, and both have seen additional turnover since. That’s not an aberration. Both chambers have seen turnover of greater than 19 percent in every election since at least 1986, with a high of 38 percent in the Senate and 43 percent in the House in 1994.
