I’m not sure I understand that site. If you roll over Iowa, it’s the same thing; Trump winning 60-some percent to Ted’s 30-some percent.
more proof of massive vote fraud in Iowa...
If you hover over the block that says “2016 Presidential Election (Donald Trump vs Ted Cruz)”, a button appears that says “Change Settings.” You can modify the settings there, and then “Draw Map” to show the new results. Have fun playing with it.
I don’t know what the source of the polling is... I haven’t taken the time to investigate it, and the source could be very important.
