Trump stumbling in Wisconsin as forces coalesce against him

MADISON, Wis. (AP) — Next Tuesday's Wisconsin presidential primary is emerging as a crucial lifeline for Republicans desperate to stop Donald Trump's march to their party's nomination. One of his worst weeks of the 2016 campaign is colliding with a state already skeptical of his brash brand of politics.
A big loss for Trump in Wisconsin would greatly reduce his chances of securing the delegates he needs to clinch the GOP nomination before next July's national convention. It could also offer new hope to rival Ted Cruz and outside groups that see Trump as a threat to the future of the Republican Party.
