Two Nevada political ads, one from Democratic Senate candidate Jacky Rosen and the other from Republican incumbent Sen. Dean Heller, have been fact-checked by PolitiFact. Rosen’s ad claims Heller voted to ‘gut’ protections for people with pre-existing conditions, which PolitiFact rated ‘Mostly True’. Heller’s ad accuses Rosen of supporting ‘sanctuary cities’, which PolitiFact rated ‘Half True’.
