You are definitely missing something. We call it "the point." Bernie Sanders is not a conventional politician. This is just one small example of the way he differs from other people who run for office. You can dislike him because of that, or for any reason you want, but it's true.

Some like the murkiness.

I like the fact that Bernie can do more than one thing at a time.

Or are you complaining that the chart does not predict the future?

Everyone knows how much time running for President takes. Just look at your chart.
I don't know about you but I want to beat the repubs in November.

If repubs get to nominate the next four Supreme Court Justices you can kiss you future goodby. Meanwhile you play these chicken shit Bernie is better than Hillary games.

It is called the primaries, that is why we compare the candidates against each other. That is why there are primaries.

In the final analysis, which is the end of next year, we'll see if the percentages are representative. So far, they state clearly that one handles responsibility over presidential run far better than the other one does.

Obama missed votes. Kerry missed votes. Most candidates miss votes. The chart that Vox manufactured would look a lot different if instead of starting at 22 months out it started at 24 months out (since Bernie missed 33 percent of the votes in Nov and Dec of 2014). Or one could compare records from the date each candidate declared or for the first X months of their campaigns. Or one could compare the number of votes cast instead of the percentage of votes missed. Bernie would have a better record than Clinton using most, but not all of these metrics. Vox however has chosen to create a really absurd comparison by looking one month (22) votes for Bernie against three months for Clinton. If Vox had wanted to make a more valid comparison they could have compared Clinton's October 2007 record to Bernie's October 2015 record. Bernie wins the comparison but instead of it being 5/83.5 it's more like 5 percent/50 percent.

quite a bit by the looks of it.

For actually giving a crap about your job.
