1. Politics

Democrats thought they had a real chance to score a big win in Georgia. In the most expensive House race ever, the Dems tried to snatch the 6th congressional district seat from the GOP. But unlike in horseshoes, close ain't good enough in politics . Republican Karen Handel edged out Democrat Jon Ossoff, showing that President Trump's flagging popularity may not be not dragging down other Republicans -- at least not yet. Democrats are now 0-4 this year in special elections. But are these results really a harbinger of the 2018 midterms ? At the very least, they show the Dems must come up with a coherent message soon, and the GOP should be concerned about challengers, even in deep red districts

2. Belgium terror attack

A man was shot and killed at Brussels Central Station in a failed bombing that Belgian authorities are calling a terrorist attack. It's the third terror attack in Europe in two days and comes just more than a year after suicide bombers killed 31 people in attacks at Brussels' airport and a train station. A small explosion went off at Central Station, sparking panic and evacuations, before the attacker was killed by police. Thankfully, no one was hurt.
