Not to mention Cnn polls have been overly favorable to Democrats all cycle. Bobby o'Rourke has followed a long line of Texas Democrats who raise insane sums of money from gullible out of state leftists before losing badly and leaving the state
78% of his donors have from Texas.
Not a counterpoint.
But it's not even worth pointing out. Most of the time when people bring up the difference between out/in state donors, they are criticizing the candidate. In this case, Cruz has raised more from out-of-state donors, so it would be hypocritical to call out only the Democrat for that. And if it's a discussion purely about usefulness, then it's worth noting that it's not like there aren't plenty of Texas donors that don't send money out of state to losing campaigns.
Also, it's not pointless to raise all that money either. What matters is how it is spent. Big campaigns that spend it on organizing and GOTV can leave lasting "infrastructure" in place that can be used over future election cycles by other candidates, one of whom might eventually win. This is particularly important in TX's case, which is a state moving towards Democrats but slower than the party wishes. Running these campaigns might seem futile, but it might help flip Texas sooner than it otherwise would.
