Trump, Bloomberg dominating early ground game in Wisconsin

At the moment, the presidential ground game in Wisconsin looks like a battle of the 70-something New York billionaires. President Trump and former New York City Mayor Michael Bloomberg have aggressively built a Wisconsin campaign presence on the ground, while Bloomberg has the airwaves virtually to himself.  Besides Bloomberg, Massachusetts Sen. Elizabeth Warren is the only one of Trump’s Democratic challengers to open a Wisconsin office and deploy paid staff here as of mid-February.
