On March 11, the Illinois House passed SB 355. It moves the primary from February to the third Tuesday in March. The Senate had passed it back on February 24. On March 12 the bill was sent to the Governor.

The bill has no impact on petition deadlines for minor parties and independent candidates. Those petitions are all due in late June, and that petition deadline is not keyed to the date of the primary.

Assuming the Governor signs it, Texas will have the earliest primary (in midterm years) of any state.
