Believe it or not, Internet Explorer does support flexbox: both the latest version, and the version before. There may be more IE users using government sites (whether they be gov employees forced to leverage it for ancient intranet use, or just some older users), but hopefully the number of those on IE <10 will still be extremely small. Global usage for IE <10 is ~0.3%, which includes many users in Asia forced to use IE for ActiveX banking; again, one would hope this figure would be far far lower in the US. The bulk of that 1.4% of global users without flexbox support are actually more likely to be on an old version of iOS Safari or pre-Chrome Android Browser, than on IE, and desktop would be a larger-than-elsewhere demographic within older users of gov sites, and within gov employees on gov workstations, so in reality the flexbox support stats could well be above average for gov sites.
